If the element is not visible, any incoming or outgoing links are not visible as well. The OutgoingLinks property specifies the list of links that starts from the current element. The IncomingLinks property specifies the list of links that ends on the current element. The ShowElements property retrieves or sets a value that indicates whether the elements are visible or hidden.
